“…To understand the contributions of various chiral fields to the KN interaction, in Fig. 5 we show the central force diagonal matrix elements of the generator coordinate method (GCM) calculation [28] of the σ, a 0 , π, ρ, and ω boson exchanges in the extended chiral SU(3) quark model, which can describe the interaction between two clusters N and K qualitatively. In Fig.…”

The chiral SU(3) quark model is extended to include the coupling between the quark and vector chiral fields. The one-gluon exchange (OGE) which dominantly governs the short-range quarkquark interaction in the original chiral SU(3) quark model is now nearly replaced by the vectormeson exchange. Using this model, the isospin I = 0 and I = 1 kaon-nucleon S, P , D, F wave phase shifts are dynamically studied by solving the resonating group method (RGM) equation. Similar to those given by the original chiral SU(3) quark model, the calculated results for many partial waves are consistent with the experiment, while there is no improvement in this new approach for the P 13 and D 15 channels, of which the theoretical phase shifts are too much repulsive and attractive respectively when the laboratory momentum of the kaon meson is greater than 300 MeV.

“…This is in particular the case of theories involving extra dimensions, such as the Kaluza-Klein mechanism (Kaluza 1921;Klein 1926) and string theory, in which all the constants (including gauge, Yukawa and gravitational couplings) are dynamical quantities (Wu & Wang 1986;Wetterich 1988;Taylor & Veneziano 1988;Witten 1984), or in theories such as scalar-tensor theories of gravity (Jordan 1949;Brans & Dicke 1961;Damour & Esposito-Farese 1992) and in many models of quintessence (Uzan 1999;Damour et al 2002a,b;Wetterich 2003;Lee et al 2004;Riazuelo & Uzan 2002) that aim at explaining the acceleration of the universe by the dynamics of a scalar field. It is A&A 514, A62 (2010) impingent on these models to explain why the constants are so constant today and provide a mechanism for fixing their value (Damour & Nordtvedt 1993;Damour & Polyakov 1994).…”

Aims. A variation of the fundamental constants is expected to affect the thermonuclear rates important for stellar nucleosynthesis. In particular, because of the very low resonant energies of 8 Be and 12 C, the triple α process is extremely sensitive to any such variations. Methods. Using a microscopic model for these nuclei, we derive the sensitivity of the Hoyle state to the nucleon-nucleon potential, thereby allowing for a change in the magnitude of the nuclear interaction. We follow the evolution of 15 and 60 M zero-metallicity stellar models, up to the end of core helium burning. These stars are assumed to be representative of the first, Population III stars. Results. We derive limits on the variation in the magnitude of the nuclear interaction and model dependent limits on the variation of the fine structure constant based on the calculated oxygen and carbon abundances resulting from helium burning. The requirement that some 12 C and 16 O be present at the end of the helium burning phase allows for permille limits on the change in the nuclear interaction and limits of the order of 10 −5 on the fine structure constant relevant at a cosmological redshift of z ∼ 15−20.

Summary. We report on a consistent, microscopic calculation of the bound and scattering states in the 4 He system employing modern realistic two-nucleon and three-nucleon potentials in the framework of the resonating group model (RGM). We present for comparison with these microscopic RGM calculations the results from a charge-independent, Coulomb-corrected R-matrix analysis of all types of data for reactions in the A = 4 system. Comparisons are made for selected examples of phase shifts and measurements from reactions sensitive to three-nucleon force effects.
